    Solution

    Let the monthly income be 100% Total monthly salary spends on rent and groceries = 57% Remaining salary = (100 – 57)% = 43% ratio between mutual fund and fixed deposit = 11 : 5 Monthly income = 77400/12 = 6450 difference between mutual fund and fixed deposit ratio = 6 Therefore, 6 ≡ 6450 1 ≡ 1075 1075 × 16(11 + 5) ≡ 43% (1075 × 16)/43% ≡ 32% 1 ≡ {(1075 × 16)/43%} × 32% = Rs. 12800
